[ITK-users] multiple itk filters in vtk pipeline issue

[Matt McCormick]

Hi Sean,

There are two filters in the ITKVTKGlue module (it has to be enabled
explicitly in your ITK build with the Module_ITKVTKGlue option) that are
used to glue together ITK and VTK pipelines. See these examples:

Hope this helps,
Matt
